On the other hand, reference numeral 9 denotes a sheet-like heat insulating material having a thickness of about 2 mm. The sheet-like heat insulating material 9 is made of, for example, a knitted body of ceramic fibers or glass fibers, a urethane sheet, a rubber sheet, or the like. Reference numeral 10 denotes a wiring accommodation groove having a depth of about 1 mm formed in a substantially T-shape on the outer edge side of the upper surface 9A of the sheet-like heat insulation material 9, and the wiring accommodation groove 10 opens at the end face 9B of the sheet-like heat insulation material 9. It is composed of a drawing groove 10A and a connecting groove 10B communicating with the drawing groove 10A and extending in the left-right direction. Reference numeral 11 denotes a power supply line arranged in a state of being buried in the wiring accommodating groove 10. The distal ends of the branch lines 11A and 11B of the power supply line 11 are detachably connected to the distal ends 3A and 3B of the conductive heating element 3. Connectors 12 and 13 for connection are attached. A temperature controller (server) for setting a desired temperature and a plug for plugging into an outlet are provided on the other end of the power supply line 11 led out from the drawing groove 1A.
